run a mile in under 6 minutes

got out to the track and ran 4 440s with 220 cooldown in between. Here are the splits:
1:18.6
1:30.1
1:26.2
1:28.4
Now granted I took a half lap breather in between these laps, all the breaks were less than 1:30 as well. This definately gives me somewhere to start. Next track time will be 880s
Although this is my first attempt at the track, I have been running a program that includes hill intervals once a week. I do three minute intervals up a fairly steep grade that really sucks and skyrockets my heartrate to 185+ by the second block. Anyway forcing your body to work through lactic acid buildup is the way to go to get faster since you wont find many people who are going to run a 6:00 minute mile aerobically.

I was in ninth grade and it was the end of the year. Time for the fitness test and THE dreaded mile. I started off comfortably and got right in behind Julie Z. who was the fastest girl and had an amazing inspiring rear view. I drafted (not really a factor in a six minute anything) behind her pushing myself to not fall more than two steps behind. At the last half track I unleashed everything and pulled ahead of her and ended up running the fastest mile I had ever run 6:02.
OK now I’m thirty and THE mile is silly since I run an average of four miles a day and am fairly certain I am in better shape now than I was then.
However, that :02 would be nice to break. I am not sure where I am in terms of single mile times as the ninth grade was THE last time I ever timed the mile.

This will be fun.
